MACHINE FOR MAKING WALL-PAPER CUT-OUTS.

Specification of Letters Patent.

Application filed April 6, 1914. Serial No. 829,755.

To all whom 2'25 may concern:

Be it known that 1, WILLIAM F. MARRES- FORD, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Machines forMaking Wall-Paper Cut-Outs, of which the following is a full, clear, andexact specification.

This invention relates to machines for making wall paper cutouts, andhas particular reference to a novel combination of driving and adjustingmeans for a design cutting-out mechanism, whereby the cutters arecapable of making a varying length of cut so as to register with thepattern as printed.

When a web of wall paper intended for a cutout is printed, it tends tostretch unevenly, so that in some instances there is a considerablevariation in the length of different patterns on the printed web. Whenit is sought to out such a pattern by a rotary cutter having a normallength of cut equal to one or a partial revolution, it is found that thecut will not register with the pattern unless the pattern is of exactlythe same length throughout. By this machine, it is possible to vary thelength of cut of a rotary cutter without tearing the paper, while themachine is running, and it is also possible to properly start the cutterin registry with the design to be out. A further result attained by thisinvention is in the use of a rotary platen in combination with a rotarycutter, and driven in such manner that the paper will neither be tornnor buckled notwithstanding a. difference between the circumferentiallength of the platen and the circumferential pitch length of its drivinggear. By this feature of the invention, the platen can be shaved downwhen worn with out requiring change of the driving gears, and also itbecomes immaterial whether the peripheral speed of the platen is thesame as that of the pitch circle of its driving gear or not. A greaterrange of adjustment is also permitted between the cutter and the platenfor controlling the depth and character of cut made in the paper.Convenient means for lateral adjustment of the cut with relation to thepattern is also provided.

The invention with reference to one form thereof is shown in theaccompanying drawing, Wherein Figure l is a side elevation of themachine embodying this invention;

gig. 2 is an end view partly in section; an

Fig. 3 is a plan view of the supply end of the machine.

The machine has a frame 1, and is driven in any suitable manner from ashaft 2 having a gear 3 which meshes with an idler 4 adjustable in theslotted segment 5, which drives a gear 6 loose on shaft 7. The shaft 7carries a cutter roller 8 having a cutter 9. The cutter 9 may be of anyform known to the art, and as herein shown consists of a large number ofsmall cutting knives or perforators arranged on the periphery of roller8 to cut the required design. The design to be out may require acomplete revolution of the roller 8, or it may be repeated, as clesired.Axial adjustment of cutter roll 8 is provided for as follows: cutterroll shaft 7 is journaled in adjustable bearings 45 which have dependingears 46. Through the latter arm the frame arm 32 passes a screw 47having a hand wheel i8. By turning the hand wheel, the bearing 45 andwith it the cutter roller 8 is adjusted parallel to the platen roll 14.The drive between gear 6 and shaft 7 is so arranged as to permit arelative shifting of the gear 6 and cutters 9, so that the cutters 9 areadjustable backward or forward through an angle of rotation suificientto enable the length of cut to be varied during a predeterminedrotation. For example, the predetermined rotation may be taken as onecomplete revolution. This result is effected by a worm gear 10 which iskeyed to shaft 7, and the gear 6 carries a worm 11 which meshes withworm gear 10. Thus, the drive is from gear 6 through worm 11 to wormgear 10, and thence to shaft 7 and cutters. 9. The worm gear 11 isprovided with a hand wheel 12 so that it can be revolved either whilethe machine is at rest or while the machine is running, and therebyshift the cutters 9. By revolving the worm 11 and thereby the cutters 9while the machine is at rest, the

cutters can be exactly registered with the printed design, while byturning the worm 11 while the machine is running, a differentialmovement between the driving gear 6 and the cutters 9 can be effectedeither forwardly or backwardly, (depending upon the way the worm 11 isrotated), and thereby the length of cut will vary relatively to thelength of the printed pattern. In other words, the cutters can be eitherangularly advanced or angularly retarded while the machine is running,and thus the length of cut made to register with the length of theprinted pattern. This will be done by the operator who, after slightexperience, will become so expert as to make the out exactly coincidewith the printed pattern, notwithstanding the variations in the lengthof the printed pattern due to the uneven stretching, warping orcontraction of the paper. This shifting of the cutters relatively to thepaper while the paper cutters are moving will be so gradual at any pointas not to tear the paper, and yet the sum of this gradual shifting,while hardly perceptible at any one point, will bring the cut and theprinted pattern back into registry. It is thus evident that while thecutter has a normal length of cut approximating its circumferentiallength, the actual cut it makes can be varied to be either more or lessthan its normal length. 14 represents a platen cylinder, which is drivenby shaft 15. The shaft 15 is carried by opposite links 16 pivoted on theframe 1 at 17 and supported by links 18 pivoted at 19 to a lever 20. Thelever 20 is pivoted on the frame 1 at 21 and is supported by anadjustable screw 22. By adjusting the screw 22 the position of theplaten relatively to the cutters 9 will be controlled, and thereby thedepth of cut. The lever 20 is provided with a chain 23 and hook 24,which latter can be engaged with a pin 25 when it is desired to hold theplaten elevated above the cutters 9 for the insertion of the paper. Inorder to provide for the variation of diameter between the platen 14:and the pitch circle of its driving gear 26, a frictional disk drive'isprovided. This consists of a disk 28 attached to gear 26 and a seconddisk 29 attached to shaft 15, between which is interposed the frictiondisk 27. The gear 26 is loose on shaft 15 and is pressed against thefriction disk 27 by spring 30 abutting against an end collar 31. Thus,the engagement of the cutters 9 with the surface of the platen 14: willact similarly to a brake and allow the friction drive to slip, so thatthe peripheral speed of the platen 1 1 will always be equal to that ofthe cutters 9, irrespective of the driving gears. This obviatesconsiderable changing of gears when the pattern is changed. For example,the pattern cutters 9 will have to be changed with each differentpattern, but

by this mechanism it will be unnecessary to correspondingl 7 change thedriving gear 26, since the friction drive will take care of allvariations without imposing any objectionable strain on the paper, aswould otherwise happen if the drive were faster or slower than theperipheral speed of the platen and cutters. Gear 6 may be changed wherethe cutting roll diameter is changed.

The gears a and 6, and the cutter roller 8' with its shaft 7, arepreferably mounted in a swinging frame 32, which swings about shaft 2 sothat the cutter roller can be dropped clear of the platen roller whendesired. The frame 32 is adjustably support 0 ed by a pin 33 which isinserted through holes 34. in frame 32 into the frame 1. By thisarrangement, the adjustable frame 32 may be changed in position toaccommodate cutter rollers of different diameters, which in the artwould normally correspond with various standard diameters of printingrolls used for printing the design which it. is desired to cut. 36represents the web which is laterally centered in the machine by atrans- 9o versely adjustable flanged roller 37, and thence the web 36runs under and over tension rollers 38 and out to the winding upmachine. 39 is a set screw for transversely adjusting the flanged roller37,

From the foregoing description, it will be seen that the presentinvention provides a machine containing adjustments for meeting thepractical conditions and variations incident to the manufacture ofdecorative cutouts. The adjustments not only permit the machine to beadjusted while at rest to properly start the cutter in registry with theclesign, but enable this registry to be maintained while the machine isrunning by varying the length of cut produced by the roller cutter fromits normal length of cut.

Various modifications and changes may be made without departing from thescope of the appended claims.

Having thus described my invention, I declare that what I claim as newand desire to secure by Letters Patent, is a 1.
